Chevrolet Camaros at SEMA are a mobile accessory catalog

Chevy's goal at the SEMA Show in Las Vegas this week seems to be to show as much of its Performance and Accessories catalog as possible. That's why it brought three different Camaros - two with V8s and one powered by a V6 - with all of the best goodies from the catalog already fitted.
We gave a more in-depth recap of the Performance Camaro V8 Concept, the Performance Camaro V6 Concept and the Performance Garage Concept already, but we figured you'd like a short recap for each. It should be noted, though, that you can order all of the items you see here for your own Camaro, so be sure to take a long, hard look at our live galleries, just in case you're in the market for some mods.
Essentially, the Performance Garage Concept and the Performance V8 Concept are the same car - the only difference is that the later features a whole host of aesthetic tweaks in addition to its aftermarket, shorty exhaust headers and 2.75-inch exhaust. (The Performance Garage Concept has been usefully placed on its side; the better to see the new parts added to the vehicle.) The Performance V6 Concept is notable because, despite being a V6, there's no shortage of performance goodies fitted. All three of the Performance Camaros benefit from items from the Camaro ZL1, which can also be ordered through the catalog.

Recharge Wrap-up: Tesla sells Model S 85 and 70D in Malaysia, Chevy Spark EV built using clean energy

Tesla will send Model S 70D and Model S 85 EVs to Malaysia for leasing to government-linked companies. Only those companies will have access to the models as a two-year lease, which will be imported and leased by Malaysian Green Technology Corporation. The plan is part of an initiative by the Ministry of Energy, Green Technology and Water to allow government officials and other influential people to get to know the electric vehicles and the benefits that come along with them. Most of the 120 vehicles available will be the 70D model, and the lessee companies will have the option to purchase the cars at the end of the two years. Read more from Paul Tan's Automotive News. Wanxiang is hosting students from Delaware in China as part of a program to learn Mandarin and visit schools and science and technology sites. Wanxiang, the auto parts company that acquired Fisker (which had manufacturing based in Delaware) and battery maker A123 Systems, will give the students tours of its solar technology facilities, among other places, and see what daily life is like for families in the region. The program helps students interested in science and technology to foster marketable skills — like learning a foreign language — that will help them get jobs in industries around the world.

The e-motors building of the General Motors Baltimore Operations complex has a new rooftop solar array and uses LED and CFL lighting, helping the building recently earn LEED Silver certification. The landfill-free facility also takes advantage of the 1.23-megawatt solar array on the grounds, helping it source six percent its energy from renewable sources. The plant has reduced its energy intensity by 15.5 percent in three years, and continues to work toward reducing consumption and sourcing clean energy. "We believe reducing our environmental footprint is good for the climate and good for our business," says GM Executive Director of Global Public Policy Greg Martin.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
